"As I have said, it is my job to investigate all corruption cases without fear or favour.

"If anyone makes a complaint, MACC will process it before classifying the complaint on whether to proceed or not," he told reporters after presenting MACC's annual report to Dewan Negara president Tan Sri Abu Zahar Ujang yesterday.

He said MACC would institute investigations following classification of the case.

While confirming that classification of the probe was under process with deputy chief commissioner Datuk Seri Shukri Abdull, Abu Kassim refused to divulge further details.

When met later, Shukri remained tight-lipped on the matter, saying that MACC was in the process of determining if there were grounds to pursue further.

"We need to find the grounds before executing further action and that is all I can say.

"This is a political case and we at the MACC do not want to be embroiled in it," he said, referring to the Selangor MB crisis.

Last Wednesday, Khalid's chief private secretary Mohamad Yasid Bidin lodged a report with the commission over allegations made against the leader.

Mohamad Yasid said he lodged the report in his capacity as a staff member of the MB's office and also because the parties who made the allegations against Khalid had not lodged a report with the authorities.

The report was based on claims by PKR secretary-general Datuk Saifuddin Nasution Ismail with regard to Khalid's business dealings and the sale of state land to a private company.
